Plastic for fixturing and workholding
I need some plastic material for workholding. I am machining a part from rectangular aluminum tubing, 4" x 3" x 1/8" thick. The finished part is 8 inches long. I am profiling one side of it, which will leave a u-shaped profile, looking from the end of the tube, so the top of the part is hanging free while I machine it. I would like to put a plastic block inside of the tube to support it while I mill off the one side. What material would be best (and preferably cheapest) for this application, and where would I find it? The blocks would need to be ~2.75" x 3.75" x 8".
